Jennifer Garner’s Biking Buddies

Mom-of-three Jennifer Garner was spotted with her three children – Violet, 8, Seraphina, 5, and Samuel, 2 – in Santa Monica, Calif. on Friday (August 15). The group were seen riding bikes after a quick stop at the store.

Rumors that the Juno actress, 42, is pregnant with her fourth child are “not true,” her rep recently told PEOPLE.

Earlier this year, the Alias alum opened up about her husband Ben Affleck.

“We are divided down a very mom-dad [line]. If it has to do with making food, or homework or anything that has to do with actually functioning, that’s a mom thing,” Jen shared of their parenting roles. “Then coming in, just as you’re getting them to bed and picking them up by their heels and swinging them around? That’s a dad thing. Anything fun, that is Ben!”
